What is refractive index?

What is refractive index?

The refractive index (also known as the index of refraction) is defined as the quotient of the speed of light as it passes through two media. It is a dimensionless number that depends on the temperature and wavelength of the beam of light. “Refractive index describes...

Applications of aspheric optics

Applications of aspheric optics

Earlier we wrote about the best technologies for custom aspheric optics manufacturing. In today’s article we will take a closer look at some of the traditional applications of aspheric optics. But first, a short recap, what are aspheric optics? What are aspheric...

The Complete Guide to Non-Imaging Optics

The Complete Guide to Non-Imaging Optics

Non-imaging optics, also known as anidolic optics, is the branch of optics concerned with optimal light transference between a source and a target. Unlike imaging optics the techniques used for non-imaging optics do not form an image of the source. Non-imaging optics...

Optics materials: Glass versus Polymers

Optics materials: Glass versus Polymers

Optical elements are made from various kinds of materials. Optical materials are usually transparent models, meaning materials with good light transmission in some spectral ranges with little absorption or scattering of light. However, absorption could also be used...

Lens for LED optic needed?

Lens for LED optic needed?

When we think about an LED optic we think about a clear plastic lens that is on top of the LED to focus or spread the light. A lens for LED will function as an optic to collect light and magnify its intensity towards the target.
